A global cyberattack Monday shut down web access to agendas, minutes and video for numerous Bay Area government agencies, including in San Francisco.
The San Francisco-based company Granicus, which provides web services for government agencies nationwide, reported the outage just before noon Monday.
The company posted updates on the outage on its website, reporting that it was caused by a global distributed denial of service attack, where a system is overloaded with connections from different systems on its name server vendor.
Granicus's downtime appears to be related to an attack that affected DNSimple, a Florida-based company that reported on its website it was “overwhelmed” by the voluminous attack despite measures in place to deal with such attacks.
The attack affected systems worldwide, according to DNSimple.
Shortly after midnight today, Granicus reported the problems had been resolved. In a letter to clients, it said the outages “appeared to be intermittent, with some people seeing no issues and others seeing some or all services as being down.”
The company's local clients include the California Public Utilities Commission, Alameda County, and the cities of San Francisco, Pinole, Monterey, Cupertino, Napa, Martinez, Walnut Creek, Petaluma, Lafayette, Fairfax and Belmont.
